Meet Mia Kish, the hero of The Well's End, a brand new young-adult novel from debut author Seth Fishman which comes out next February. We've got the exclusive cover reveal, plus one more illustration by Hark! A Vagrant creator Kate Beaton that shows the whole cast.

Here's the full version of the Kate Beaton artwork above, showing Mia, in the moment before she breaks a hole in an iced-over lake and swims through it:

And here's the official synopsis of Fishman's book:

A childhood accident, a bizarre outbreak, and an impossible discovery…

Mia Kish is afraid of the dark. And for good reason. When she was a toddler she fell deep into her backyard well only to be rescued to great fanfare and celebrity. In fact, she is small-town Fenton,Colorado’s walking claim to fame. Not like that helps her status at Westbrook Academy, the nearby uber-ritzy boarding school she attends. A townie is a townie. Being nationally ranked as a swimmer doesn’t matter a lick. But even the rarefied world of Westbrook is threated when emergency sirens start blaring and the school is put on lockdown, quarantined and surrounded by soldiers who seem to shoot first and ask questions later. Only when confronted by a frightening virus that ages its victims to death in a manner of hours does Mia realize she may only just be beginning to discover what makes Fenton special.

The answer is behind the walls of the Cave, aka Fenton Electronics. Mia’s dad, the director of Fenton Electronics, has always been secretive about his work. But unless Mia is willing to let her classmates succumb to the strange illness, she and her friends have got to break quarantine, escape the school grounds, and outsmart armed soldiers to uncover the truth about where the virus comes from and what happened down that well. The answers they find just might be more impossible than the virus they are fleeing.

Here are Beaton's illustrations of the book's entire cast of characters:
